You might think that the moral of a story coming out of Sweden would be “Don’t feed the trolls”, but, no: according to the Hallands Post there is a problem with the wild boars that are re-establishing themselves in the forests of southern Sweden: the hunters put out food for them, and then they get tooth decay from eating Danish pastries which people throw away.
(The idea isn’t to shoot them while they are eating but to help the through the winters. Even this backfires to some extent, because the well-fed mothers give birth too early in the springtime and their piglets freeze)
The real beastliness of the boars is that they lay waste to so much forest floor. My chanterelle collectors report that this vastly reduces the chances of getting a decent crop, and are furious about the whole business.
